T 0 aZZ whom it may concern:

Be itknown that I, OTTO ULLRICH HARTUNG,

of Leipsic, Saxony, Germany, have invented a new and useful Balloon with Machinery for Steering,(for which I have obtained a patent in Great Britain, No. 2,469,.dated January 31, 1884; in France, No. 160,212, dated February 9, 1884.; in Germany, No. 26,930, dated September 6, 1883,) of which the following is a specification.

My invention relates more particularly to the means of propelling and steering balloons.

In the accompanying drawings, Figure 1 is an elevation, and Fig. 2 a plan, of a propelling and steering apparatus embodying my invention, whileFigs. 3 to 12 show details and modifications.

From the oblong balloon B are suspended, by means of a system of straps, the longitudinal main beams A A, connected with each other by stays and serving to support the ma chinery and the gondola or car. Right and left of the car, and parallel with the beams AA,are suspended the shafts W N, provided with screw propellers S and S S and S. Bectangularly to the beams A and A, Fig. 2, and fixed to the same is a cross-beam, I), carrying the circularly-curved tracks G and G, which again support the bearings of the screw-shaft W. The shafts W V are supported partly by the bearings Z Z 2 1, adapted to slide on the curved tracks G G, and partly by the central bearings, L and L, pivoted to The shafts are steered from the inner bearings, Z and Z, provided with lateral eyelets 1 2 3 4., (see Fig. 3,) for attaching the ropes O 0*, serving to set the said bearingsin motion and retain them in the desired position. The opposite ends of the ropes are attached to the drum T at the points 1'2 3'4. By turning the drum in the direction of the arrow E the ropes O and (3 are wound on, while the ropes C and O are wound off. Consequently, the bearings Z and Z are shifted in the direction of the arrow J,and the shafts \V and "W1 turned on the pivotal bearings L and L.

The shaft W is supported in the center by the pivotal bearing L and at the ends by the bearings Z and Z, adapted to slide on the tracks and G. The latter bearings have eyelets 5, 6, 7, and 8. as shown by Fig. 4, for attaching ropes J J, J and J the opposite vends of which are attached to the drum U at the points 5 6'7 8. By turning the drum U in the direction of the arrow H the shaft is shifted in the direction of the arrows M and M, the ropes J and J being wound on the drum U and simultaneously the ropes J and J wound off. By turningthe drum U in the direction of the arrow K the shaft WV is pivoted with its central bearing in the direc tion of the arrows N and N. The two drums T and U are mounted on thesame shaft, as shown in Fig. 1, but coupled with the same in such a manner that each drum may be turned independently of the other.

The crank-shaft V, Fig. 1, is set in motion by any suitable engine or byha-nd, and transmits its motion to the shaft W 'by means of the bevel-wheels a and b, the shaft E (see Figs.

(No model.) Patentedin Germany Septcmland 5) and the bevel-wheels 0 d, the shaft E being held at its upper end in a pivotal bearing, L, which also forms a bearing for the shaft NV", and is secured to the beam D by a pivot the axis of which coincides with that of the shaft E. If the end bearings of the shaft W are shifted horizontally along their curved track, the bearing L is turned and the wheel at rolls on the wheel 0.

Fig. 6 illustrates the method of driving the screw-shafts W and W from the crankshaft V. The shaft V sets in motion a pair of bevelwheels, 6 and f, the latter being mounted on the shaft 9', connected with the shaft h by a uni versal coupling, 0. The shaft It drives the propeller-shafts V or W by means of a pair of bevel-wheels, t It. The lower end of the shaft 9 is supported by a stepbearing, forming also a bearing for the horizontal shaft '0, and being adapted to pivot on the same. To preventthe shaft 9 from leaving the bearing r, that part which enters the said hearing has an annular groove, 3 turned on, as shown in Fig. 7, through which pass a pair of pins, as and 0c, driven into the bearing r, as shown by Figs. 7 and 8. In the same manner as the shaft 9 is connected with shaft V the shaft h is also connected with shaft W. Consequently the shaft W may be shifted with its bearing along the track or slide G to the right or left until the axes of the shafts g and h form one straight line. The upper extremity, of the shaft 9 is held in a bearing, Z, provided with rollers m and n, adapted to run along aT-shaped rail or track, p, forming a circular arc with the shaft 0 as a center, and fixed to an angleiron, q, which is secured to the frame carrying the car. The rollers m and n are grooved in order to prevent a deviation of the shaft 9 perpendicular to the plane of the track 19.

Fig. 9 shows in detail the pivotal bearing L or L. The base-plate B, attached to the cross-beams R and B, Figs. 1 and 2, carries the pivot O of the forked bearing F. A pair of collars, p and r, prevent the shaft WV from being longitudinally shifted in the bearing F. The rising and falling of the vessel or balloon is effected by the screws X and Y. (Shown in Figs. 1 and 2.)

Fig. 10 illustrates a method of transmitting motivepower from the main driving-shaft V to the screw-shafts by means of bevel-wheels r and shaft X. On the shaft Xis also mounted the bevelwheel v, gearing into the wheel to, mounted on the screw-shaft V Immediately over the wheel 1) is fixed to the shaft X, the small wheel 8, gearing into the wheel 8, mounted on the shaft Y. The latter sets in motion the vertical shafts Z Z by means of bevel-wheels t t, and the shafts Z Z turn the shafts W and W by means of bevel-wheels wand u. The upper ends of the shafts Z Z are guided in bearings attached to the longitudinal beams, while the lower ends are held in the covers of the bearings L and L, which may be turned about the shafts W and W. The steering of the shafts W W is effected by the same means as described above with reference to Figs. 3 and 4, so as to alter their angle with the beams A A, as may be desired.

Figs. 11 to 13 illustrate a convenient method of securing the vanes of the screw-propeller in their relative position, which consists in connecting them with each other or with the propeller-shaft by wires. Each of the vanes a, b, and c, Fig. 11, is attached at the inner end to one of the arms of aboss or core mounted on the shaft to, while two points of its outer extremity are held fast by wires, cords, or other ties. As shown in Fig. 13, two flat irons are riveted to opposite sides of each vane, and to these fiat irons are riveted two eyelets, 0 0. The corresponding points 1, 2, and 3.0f the vanes a, b, and c are connected with each other by three wires, 8 s 8 so as to form a triangle, while the corresponding points, 4, 5, and 6, of the same vanes are connected with each other by wires s s s, so as to form a sec ond triangle, as shown in Fig. 11.

In orderto prevent a lateral deflection of the vanes the shaft w, Fig. 12, is provided with a pair of carriers, m and m, which are con nected with the vanes a, b, and c by wires d d. The points 1 and 4 of the vane a are joined to the carrier at by wires d and d and to the carrier m by wires d d Each of the other vanes, 12 and c, is also connectedwith the carriers in and m by four wires in the same manner.

What I claim is 1. In aerial vehicles or vessels, the combination of horizontal screw-shafts W and WV, adapted to turn on vertical pivots, with means for producing a simultaneous and symmetrical pivotal motion of the two shafts, substantially as described, and for the purpose specified.

2. The combination of the concentricallycurved tracks G G, mounted on beams A, A, and D, with screw-shaft W pivoted in the center of the track and provided near its extremities with bearings adapted to slide on the said curved tracks for the purpose of setting the screwshaft at any desired angle, substantially as described.

3. The combination of screw-shafts W W with pivotal bearings L L for the centers of the said shafts, and circularly-curved tracks or slides adapted to support the extremities of the shafts, substantially as described.

4. The mechanism for settingin motion the screw-shaft W or WV, comprising the shaft g and h, bevel-wheels cf, bevel-wheels 2' 7c, coupling 0, double bearings r, movable bearing 1, and curved guide 19, substantially as described.

5. The appliance for simultaneously controlling the angle of the screw-shafts W, NV, and W, consisting of ropes O G and ropes J 5 J connected with the end bearings of the screw-shafts, and rope-drums T and U, mounted on the same shaft, substantially as described.

5. The combination of vanes a b 0 with wires or ties sand 8 substantially as described.

In testimony whereof I have signed this specification in the presence of two subscril ing witnesses.
